Blending mode

0 - no blending
1 - additive rendering instead of alpha
2 - diffusion color (col parameter in CVertex) adds to texture color, instead of multiplying
4 - like 2, but "smooth addition"
6 - multiplication & dividing by 2 after
8 - addition, then 127 is subtracted from each component
32 - disable alpha channel
64 - color of pixel is multiplied by target pixel color
128 - disable AA
